Impressive . Well worth the time spent and more to come I`m sure

No real updates here, I've continued to tweak things as I've had time.

I re-fitted the Tial bypass valve to add a bit of noise/drama and developed a custom tune for the DCT gearbox to increase shift speeds, which has made a massive difference.

Will you be making this available for people with DCT and if so will it be for just the Maxxecu ?

Yeah, i've been doing DCT tunes for final drive changes on E9x M3s for a few years now, along with line pressure increases for higher power cars etc.

What s/w do you use for that ?

WinOLS to make the file changes, but I have my own flasher I use to flash the modified bins. It's much less clunky than flashing modified 0DA files with WinKFP (I used to do this).

I've been rather impressed with your flasher Martyn, once we got round the main issue (me not understanding what I was doing

)

Respect…way too far from my comfort zone …I’ll just stay in my own limited universe

Any more updates on this Martyn? This has definitely been one of my favourite project threads in a long time!!

I'm quietly hoping you've been cooking up the S65 swap now
